BEARING-BLOCKS FOR EQUALIZING-BEAMS.

Patented Mar. 19, 1918.

Application filed January 19, 1918. Serial No. 212,778.

To all whom it may concern:

Be it known that I, KENNETH RUsHToN, a citizen of the United States, residing in Philadelphia, Pennsylvania. have invented certain Improvements in Bearing -Blocks for Equalizing-Beams, of which the following is a specification.

My invention relates to certain improvements in the equalizing gear of a locomotive.

The object of the invention is to provide means for adjusting-the fulcrum blocks of the equalizing beams so that the pivot pin can be located in different positions, according to the weight desired on the driving wheels.

In the accompanying drawings Figure 1, is a side view of part of a locomotive frame and an equalizing beam, showing the fulcrum pin and blocks; Fig. 2, is a sectional view on the line 2-2, Fig. 1; and Fig. 3, is a perspective view of one of the fulcrum blocks.

1 is the frame of a locomotive having acavity 2 in its under side for the reception of a fulcrum block 3. 4 is one of the equalizing beams having a cavity 5 in its upper surface for the reception of a fulcrum block 6. The two fulcrum blocks 3 and 6 are identical, in the present instance. Each block has a series of three recesses 7, 8 and 9. on one face, and two recesses 10 and 11 on the opposite face.

12 is the fulcrum pin having heads 13, which extend on each side of'the fulcrum blocks 3 and 6. A flange 14 on the beam extends on all sides of the cavity 5, which holds the fulcrum block 6 from moving laterally or longitudinally. Between this fulcrum block 6 and the base of the recesses are liners 16, of metal, or other suitable material for bringing the parts into alinement. The cavity 2 in the frame, in the present instance is open at the sides and lugs 15 prevent the longitudinal movement of the block 3. The blocks are preferably beveled at the ends to allow for clearance.

By the above construction, the pin 12 can be located either in the central'recess 7, as shown in Fig. 1, or in either of the recesses 8 and 9, or if an adjustment between these pins be desired, then the blocks can be turned over and the pins located in either of the recesses 10 or 11.

By this construction I am enabled to make five adjustments, which will be ample for all ordinary purposes.

It is often desirable, in assembling equalizing gear of a locomotive, to change the position of the pivot of the fulcrum pin and by the construction above described this can be accomplished by merely jacking up the parts and shifting the pin or reversing the blocks.

I claim 1. The combination of a frame; an equalizing beam; two blocks, one mounted on the frame and the other on the beam, said blocks having a plurality of recesses; and a pivot pin arranged to be located between the two blocks and in the recesses.

2. The combination of a frame having a cavity in its under side; an equalizing beam having a cavity in its upper face; a fulcrum block mounted in the cavity of the frame; an opposing fulcrum block mounted in a cavity in the beam; said blocks having transverse curved recesses; and a headed fulcrum pin adapted to be mounted in any of the recesses of the blocks.

3. A fulcrum block having a series of curved recesses on one face; and a series of curved recesses on the opposite face out of line with the first mentioned recesses.

at. The combination of the frame of a locomotive having lugs spaced apart; a fulcrum block mounted between the lugs, said fulcrum block having three transverse recesses on one side and two transverse recesses on the opposite side out of line with the first mentioned recesses; an equalizing beam having a flange forming a cavity in the upper surface of the beam; an equalizing block, similar to the first mentioned block, mounted in said cavity and having three transverse recesses on one side and two transverse recesses on the opposite side; and a fulcrum pin having a head at each end and adapted to be mounted between the two blocks in any pair of recesses.

In witness whereof I affix my signature.

KENNETH RUSHTON.
